According to ParrotFeather.com, lovebird eggs take 21 to 24 days to hatch. Lovebirds lay clutches of four to six eggs, usually laying eggs every second day until they have laid a full clutch.
Once lovebird chicks hatch, they should be left alone and should not be hand-fed for the first few days. Their mother feeds them a regurgitated formula that includes vital enzymes to aid their initial development. After a week to 10 days, breeders usually remove the chicks from the nest and begin hand-feeding them. Hand-fed chicks are social and more accepting of handling by humans as adults, making hand-fed lovebirds suitable pets.
